STRIPPING MECHANISM FOR WRINGER-ROLLS.

Application led October 2, 1919. Serial No.

To all whom z't may concern:

Be it known that I, THOMAS J. BONNI- wnLL, a citizen of the nited,States,and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inStripping Mechanism for lVringer-Rolls, and l do hereby declare that thefollowing is a full, clear, and exact description ofthe same, referencebeing had to the accompanying drawings, and to the numerals of referencemarked thereon, which form a part of this specification.y

This invention relates to an attachment for a wringer to provide a meansfor preventing articles after passing between the wringer rolls fromaround either thereof by stripping or diverting the articles from therolls if any tendency for the articles to cling to the rolls occurs.

lt is-an object thereforeof this invention, to construct a wringerhaving a plurality of adjustably mounted stripper bars adjustable to anyposition according to wearing of the rolls, for contact with the wringerrolls on efectually prevent adhering of articles to the rolls for eitherdirection of operation thereof. Y

@ther and furt-her important objects of this invention` will be apparentfrom the disclosures in the ldrawings and specification.

The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

Description..

The wringer consists of end uprights 1 Specification of Letters Patent.

becoming wrapped ,Y

each side of eachroll toV rolls 3 and 4 in a usual and well knownmanner. vThe shafts for the wringer rolls are provided with intermeshingpinions 5 and 6, to insure positive and simultaneous operation of bothrolls in opposite directions when one thereof is operated in the usualmanner. by means of a crank placed upon the shaft extension 7. A waterdrain board 8, is mountedbeneath the lower roll in a usual,manner.

Secured between the uprights 1 and 2, on each side of the wringer, Aaretransverse boards 9, positioned slightly above the upper roll 3, andtransverse bars 10 are also secured on each side of the wringer to theuprights 1 and 2, slightly below the roll 4.

The stripper bars for the upper roll are shown clearly in Fig. 2, andare designated by the reference numerals 11. rlhey are preferably.though not necessarily, constructed of wood, but ofcourse may be ofmetal or other material. having beveled lower surfaces which rest bygravity upon the top surface of the roll 3.' At each end of each of thestripper bars 11, transverse pins or rods 12 are provided, extendingtherethrough so that the bars are loosely retained thereon, permittingadjustment of the stripper bars also tolt any size roll. vSaid rods 12,have no connection with the wringer frame, but merely abut against thebars 9, and prevent overturning of the stripper bars 11, resting bygravity on v`the roll 3 when the roll 3 revolves. .As shown, theuprights 1 and 2 are provided on their inner surfaces with angle irons13, which constitute a part of the usual Awringer constructions. IThestripper bars 11, are provided with block sections or extensions 14 attheir ends, which 'are squared off to rest in the upright angle bars 13,and serve also to prevent overturnin of the stripper bars 11 on thewringer rol.

Beneath the lower wringer roll 4, another set of stripper bars 15 isprovided, which at their ends are loosely engaged on transverse rods 16,looselyA mounted in the -Wringer frame,

and abutting the boards 1.0. For the purpose of retaining the lowerstripper bars l5 `upwardly in contact with the undersurface of the roll4,a pair of springs 17 are provided for each of the ystripper bars,bearing upwardly therebeneath near Patented Apr. 119, 1921. A

each end thereof and secured in position on the respective boards 10.

I Operation.

The upper stripper barsA 11, rest upon the top roll 3 by gravity, thebeveled lower surfaces thereof riding upon the surface of the roll. Therods 12 which extend loosely Vthrough each end of the stripper bars 11,

prevent overturning thereof, and said rods atitheir ends abut againstthe boards 9.

In some types of wringer constructions, the boards 9 are omitted, butgenerally the upright angle irons 13 form a part of this structure, andthese may be utilized to prevent overturning of the stripper bars 11.Accordingly, I haveshown block sections 14,.l secured to or forming apart of the stripper bars 11, engaging loosely in the upright angle barsturning of the stripper bars. rods'12 may be used, or the angle bars 13and block sections 14, toprevent overturning of the stripper'bars,butthis will depend upon the type of wringer with which the stripperbars are associated. l

Similarly the lower stripper bars 15 contact against the under surfaceof the roll 4, and are held thrust upwardly against the roll by the leaf0r any other type of springs 17, securedA to theboards 10. .Similarlythe transverse bars 16, loosely engaged through the stripper bars 15,prevent overturning of the stripper bars by rotation of the roll.

It is obvious that many ,other ways and means for disposing, attachingor assembling the stripper bars with the wringer are possible wherebythe stripper bars are held in operative relation by gravity or resilientmeans, and capable of displacement movement from the' rolls, but allsuch'modifcations fallwell within the scope of my invention.- In placeof 'two stripper bars 13 and serving to prevent over Either the.

f substantially to the contour of the roll at its contacting portiontherewith.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I therefore do not purposelimiting the patent granted otherwise than necessitated by the priorart.

Claims.

1. In a wringer, the combination with the rolls thereof, of stripperbars contacting with the rolls, and means for securing said bars inplace, comprisinga transverse rod at each end, extending transverselythrough said bars, to non pivotally secure said bars within the wringerframe.

2. In a wringer, the combination with the rolls thereof, of a pair ofparallel stripper baars arranged to Contact with each roll, a.

. date the same for different sized rolls and to take up wear.

In testimony whereof I have hereunto subscribed my name in the presenceof4 two subscribing witnesses. i
